Title: Chlorinated rubber products
IPC: C08L15/02
Filed: 1936-12-15
Abstract: A chlorinated rubber containing 2-20 per cent of chlorine, is incorporated with a fully chlorinated rubber containing more than 55 per cent, preferably about 65 per cent of chlorine to obtain a product which is flame-resistant and plastic and elastic.  The properties of the product depend upon the degree of chlorination, and the proportion of the partially chlorinated rubber.  A mixture containing one part of 6 per cent chlorinated rubber to five parts of fully chlorinated rubber is a brittle solid; with proportions 1 : 2 an elastic tough material is produced which can be rolled into sheets; proportion 2 : 1 gives a soft, slightly tacky, flexible product.  Small amounts of plasticizers such as tricresyl phosphate, or dibutyl phthalate may be added, but are not generally necessary unless the total chlorine content exceeds 50 per cent.  Stabilizers and antioxidants may also be added.

Abstract: 1300015 Vertically adjustable chairs AMERICAN HOSPITAL SUPPLY CORP 23 July 1971 [16 Feb 1971] 34718/71 Heading A4J [Also in Division F2] The base of a dentist's chair which may be raised manually or by transmission of power from a reversible motor 24 and locked against downward movement, comprises an upper frame 17 secured to the underside of the chair 11, a lower frame resting on, or secured to the floor, a pair of laterally spaced, inter-connected sets of linkage mechanisms 23a, (23b), Fig.4 (not shown) connected to the upper and lower frames and to a member 33 having a threaded bore through which a screw shaft 32 passes such that rotation of the screw shaft causes the member 33 to move axially along the shaft thereby expanding or contracting the linkage mechanisms which causes the chair to be raised or lowered. The screw shaft 32 is connected to the output shaft of the motor through a one-way clutch 35 and a reduction gear assembly 34, the one-way clutch allowing rotation of the screw shaft in the direction in which the chair is raised when the motor is de-energized thereby allowing for manual lifting of the chair and the reduction gearing preventing rotation of the shaft in the direction in which the chair is lowered when the motor is de-energized thereby locking the seat against downward movement. Lowering of the chair is effected by reversing the motor such that screw shaft 32 rotates, the chair exerting an axial force on member 33 thereby tending to increase the speed of rotation of shaft 32 which is limited or braked by the speed of the power-driven motor shaft 31 and output shaft 38.

An electromagnetically-tripped switch comprises fixed contacts 5 co-operable with a spring bow 6 biased by compression springs 10 and carried by an arm 8 pivoted at 9 and biased by a tension spring 12. The contacts are closed by rotation of a handle whose arm 17 engages the arm 8 which is held in the closed position by a latch 25 formed from an arm 18 pivoted at 20 and biased anti-clockwise by a spring 21. To open, the arm 16 is raised thereby depressing the arm 18 by means of a link 26 and allowing the spring 12 to rotate the arm 8, the stress in springs 10 determining the time lapse between the disengagement of members 8, 25 and the separation of the contacts 5, 6. These contacts are in series with a solenoid coil 30 whose armature 41 engages a slot 43 in the arm 18, so that upon the occurrence of a low overload, movement of armature 41 trips the switch. The coil 30 is in series with a fuse 35 mounted on a carrier 36 and engaging clips 34 in a recess 40 of the switch casing 1, a heavy overload causing blowing of the fuse 35 and tripping of the switch. The coil 30 may be in parallel with a bi-metallic element which opens the parallel circuit on low sustained overload to produce electromagnetic tripping of the switch. The link 26 may be arranged so that electromagnetic tripping moves the handle to the " OFF " position. The contacts 5 may be mounted on compression springs, additionally or alternatively to the bow 6 which may be laminated. A three-phase A.C. circuit may be controlled by three of the above switches or a D.C. circuit by two switches, only one of which is in series with a solenoid and a fuse. The terminals 27, 38 may be replaced by contact plugs.

Abstract: 282,829. Grenaudier, L. Dec. 30, 1926, [Convention date]. Addition to 279,516. Pulp, preparation of.-A modification of the process of the parent Specification consists in removing the ink through the formation of an insoluble scum by treating the pulp of the paper which is to be freed from ink with a very weak alkaline solution of carbonate of soda in ordinary water, 1 in 800 for example, the mass being heated and agitated throughout the treatment to produce a scum which carries off the pigment, the soap formed being rendered insoluble if necessary by addition of a metallic salt or an alkaline salt which effects the salting out. The insoluble scum may be produced by decomposing the soap formed with an acid so as to liberate the fatty acids of the soap which fatty acids are insoluble in water and are adapted to collect on the surface as a scum by reason of this low density. The agitation may be effected by boiling or by an air blast or by both applied during the mixing or stirring. A certain proportion of soluble soap may be added to increase the precipitation or salting out, and the capillarity of the solution employed may be varied by the addition of gelatine, albumen, casein, glucose and the like, and loading and bleaching agents such as bisulphites, hypochlorites and the like may also be added.
